制作时间戳和时间戳转标准日期时间等

经过验证的如下：

        /// <summary>
        /// 将Unix时间戳转换为DateTime类型时间
        /// </summary>
        /// <param name="d">double 型数字</param>
        /// <returns>DateTime</returns>
        public static System.DateTime ConvertIntDateTime(double d)
        {
            System.DateTime time = System.DateTime.MinValue;
            System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1));
            time = startTime.AddMilliseconds(d);
            return time;
        }

        /// <summary>
        /// 将c# DateTime时间格式转换为Unix时间戳格式
        /// </summary>
        /// <param name="time">时间</param>
        /// <returns>long</returns>
        public static long ConvertDateTimeInt(System.DateTime time)
        {
            //double intResult = 0;
            System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970,1,1,0,0,0,0));
            //intResult = (time- startTime).TotalMilliseconds;
            long t = (time.Ticks - startTime.Ticks)/10000;            //除10000调整为13位
            return t;
        }

以下方法：未经过测试！！！！！

制作时间戳：

 /// <summary>
        /// DateTime时间格式转换为Unix时间戳格式
        /// </summary>
        /// <param name="time"> DateTime时间格式</param>
        /// <returns>Unix时间戳格式</returns>
        public static long ConvertDateTimeInt(System.DateTime time)
        {
            System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1));
            return (long)(time - startTime).TotalSeconds;
        }

调用方法： long time = ConvertDateTimeInt(DateTime.Now);

时间戳转标准时间：

 private string GetTime(string timeStamp)
        {
            DateTime dt = DateTime.Now;
            if (timeStamp.Length == 14)
            {
                dt = DateTime.ParseExact(timeStamp, "yyyyMMddHHmmss", System.Globalization.CultureInfo.CurrentCulture);
            }
            return dt.ToString("yyyy-MM-dd HH:mm:ss");
        }

调用方法：var  datetime = GetTime(transactionTime);
